Abstract
A translucent structure includes a translucent substrate and an antireflection layer provided on a visible side of the translucent substrate so that reflectivity of the translucent structure based on an SCI method is 3% or less. A visible-side outermost surface of the translucent structure includes a concave and convex structure as follows. The concave and convex structure includes a first convex portion and a second convex portion. The first convex portion has a diameter exceeding 10 μm and 185 μm or less in a specific section, and a specific maximum height is 0.2 to 8 μm. The second convex portion has a diameter exceeding 1 μm in a specific section, the number thereof is 0.0001 to 1.2 per 1 μm2, and a specific average height thereof is 0.1 to 8 μm.
